Chapter 1002 The Truth About the Murder Case ([-])
"That's a good question."

Lin Chuang praised it.

If it is compared to talking about cross talk, this question is the one that is praised; if it is compared to composition, this question is the key word for succession and transformation.

"Where did the hydrogen chloride come from?" Lin Chuang asked himself and answered, "Please take a look."

Lin Chuang picked up the light bulb: "This light bulb was originally on the roof of the cabin. It didn't stay well. Why did it fall on the salt bag? And it still fell on the open salt bag?"

Seeing that everyone was confused, Lin Chuang's vanity was satisfied, so he solved the mystery.

"The reason is very simple. Someone deliberately put the light bulb on the salt bag. The purpose is to use it to heat the salt and make it produce hydrogen chloride gas. Hydrogen chloride has a suffocating smell and is a strong irritation to the upper respiratory tract. Eyes, skin, and mucous membranes have a strong corrosive effect, and inhalation of large amounts will make it difficult for people to breathe and even suffocate."

After hearing Lin Chuang's explanation, everyone showed expressions of enlightenment. Only the young man in Xilinling still had doubts: "Sir, can a light bulb be placed on salt to produce hydrogen chloride?"

Lin Chuang replied: "It is clearly written in chemistry books that salt will decompose into hydrogen chloride at high temperature. At the same time, other impurities in the salt will produce other gases, and most of these gases are poisonous."

"Sir, what is the wattage of the bulb?" Xilinling asked again.

"200 degrees."

"The 200 degrees of the light bulb refers to its power, not its temperature. At the same time, the tungsten filament that makes it glow and heat is separated by a layer of glass, and it is not exposed. Will it generate high temperature?" Xilinling asked.

Lin Chuang secretly said: "The young man in question has the potential to be a scientist, and the question is on the right track. Fortunately, I did the experiment last night, otherwise, he would have really stopped asking today."

"Yes." Lin Chuang replied firmly: "Last night, I did an experiment, using a 200-degree light bulb on the salt, and within 20 minutes, Vice Captain Ning was so smoked that he couldn't stand it. Yes No, Vice Captain Ning?"

"Yes, the humble position can prove that Mr. Lin is telling the truth." Ning Xiaobo stood up and replied.

"Oh, that's no problem." Xilinling sat down.

"Well, this explanation is reasonable and fits the circumstances of the murder scene." Yunzi Nakano nodded, affirming Lin Chuang's explanation.

Lin Chuang glanced at Takaya Aoki.

Aoki Takaya said: "Lin Sang, don't look at me, and don't ask for my opinion, I just listen and don't talk."

Lin Chuangxin said: "You still understand the truth."

Then he said: "Since everyone has no objection, then I will continue."

Everyone nodded, Yunzi Nakano said: "Quickly tell me, I am eager to know the final answer."

"Okay. The source of the poisonous gas has been found, and the murderer's method of killing has been found. Although the crime process is speculative, it is completely logical. Let's conclude that this conjecture is correct. Then, who is the murderer?"

"From the point of view of the method of making the drug, the murderer must meet three conditions. First, he must understand the principle that salt will decompose into hydrogen chloride under high temperature conditions, that is to say, he must have certain chemical knowledge; second, the person on board Just like me, although I also understand this principle, but I am not on the ship, I have been with Mr. Nakano, so I can’t carry out the killing. Unless I have the legendary stunt of killing thousands of miles, then I will be very good.”

"Hehehe..." After Lin Chuang finished speaking, the people below chuckled.

"Thirdly, this person has had contact with Liu Deshan. Liu Deshan may not know that salt has an anti-inflammatory effect. Even if he knew, he may not go to the bilge after it is full of hydrogen chloride. Therefore, the murderer must have met Liu Deshan."

"After I saw the murder scene, I had this idea in my mind. However, as far as I know, there are only boatmen on board, and few of them can read. They only know salt, salt, acetic acid, how can they know chemistry? So , I'm at a loss.

It wasn't until after interrogating Lu Shutao that I suddenly realized.

Lu Shutao graduated from the Chemistry Department of Waseda University in Japan, and he also carried chemistry books in his luggage.That is to say, he satisfies the first and second conditions.

However, in his statement, he only said that he had contact with Hua Yichang and Ye Ziqiong, but he had no contact with Liu Deshan, or even spoke to him.

Then I thought, is he hiding it on purpose?
Just after returning from the Jianglong, I interrogated the boatman again.A boatman named Chen Amao confessed that on the night of the accident, he went out to pee and saw Lu Shutao quietly go up to the third floor.Chen Amao felt strange, why did this Mr. Lu go to the third floor in the middle of the night?You don't have to climb up to pee, do you?Not to mention going to the top floor to see the scenery in the middle of the night.In order to satisfy his curiosity, Chen Amao hid aside and observed Lu Shutao's whereabouts. He knocked on the door of cabin 3, went in and said a few words before coming out. It is not clear what he said.

I asked Chen Amao, what time was it at night when I saw Lu Shutao?

Chen Amao couldn't tell, he just said that he had already slept, and it was definitely midnight, but he didn't know the exact time.

The concept of midnight is very broad, and it is difficult to determine the specific time. According to traditional Chinese sayings, from eleven o'clock to one o'clock in the middle of the night is called Zi time, and any period within this interval can be called midnight.After this interval, we call it the second half of the night.

The autopsy results in Xilinling showed that Liu Deshan died between [-]:[-] and [-]:[-] at night, that is to say, Liu Deshan probably didn't know the anti-inflammatory effect of salt before [-]:[-], and then went to the end. cabin.

Chen Amao's confession just proved that Lu Shutao went to Liu Deshan's cabin during this period of time. What did he do?Liu Deshan died shortly after he went there. I don't need to explain what this means, right?
Furthermore, he had been to Liu Deshan's cabin. When I interrogated him, he didn't reveal the slightest bit, only saying that he went to bed early.If there is no ghost in his heart, why did he cover it up? "

Yunzi Nakano and others nodded in agreement.

Lin Chuang took a look at Wu Sibao and saw that Wu Sibao was actually taking notes with a pen, so he couldn't help but nodded secretly: "Rough but careful, he knows that he can use the details I mentioned."

"Director Lin, how did the light bulb get onto the salt bag? Is there any evidence to prove that this was also done by Lu Shutao?" Fairy Shi Gong asked.

"Yes, yes, Miss Fairy got the point." Lin Chuang picked up the light bulb and said, "This light bulb is installed on the roof of the hold. Since the hold is full of salt bags, standing on the pile of salt bags, It is easy to tear off by hand.

Moreover, I asked Li Yuewang, and he said that for the convenience of carrying the salt bags, and there were no valuables or key equipment in the bilge, so the bilge door was not locked or guarded, and anyone could come in and out.

Therefore, Lu Shutao has the conditions to enter and exit.

But to be honest, I really have no evidence to prove that he went in. "
